H. l1:), LlNToN TEXTILE SPOOL Jan. l5, 1935.

Filed March 2O, 1934 Patented Jan. 15, 1935 UNITED STATES PATENT OFFICE 7 Claims.

This invention aims to provide an improvement in textile spools and bobbins, with reference more particularly to the class of such devices wherein heads of a material characteristically different from that of the barrel are designed to be joined thereto inseparately.

The primary object is to simplify the construction and reduce the manufacturing cost of said articles by uniting the head and barrel parts with a minimum of workmanship and material necessary, and with an effectuality great enough to preclude subsequent separation or loosening from each other without breaking entirely apart under very abnormal strains or blows.

Another paramount object is to produce a spool or the like which will be strong and durable enough to withstand indefinitely the hard and rough usage that such articles commonly receive in textile mills by dropping and throwing about into containers. l

Other objects, in addition to the general concept and advantages of the inventio-n will be apparent and best understood from the following description with reference to the attached drawing illustrating one practicable embodiment of the same in an ordinary loader spool.

In said drawing:

Fig. l is a perspective view, partly in section, showing a spool with its head and fastening means at one end in applicative relation to the barrel;

Fig. 2 is a side elevation, also partly in section, representing the finished spool;

Fig. 3 is a perspective representation of the spool head as Viewed from its under or inner side; and

Fig. 4 is a fragmentary longitudinal section illustrating a slight modication in the form of the spool.

The spool of the illustrative construction includes a barrel 5 of conventional cylindrical form. This barrel is preferably made of wood which has properties especially appropriate to the purpose in addition to low cost, but it may be made satisfactorily from some other solid material that is sufficiently light, such as compressed nbre or even certain metals. It is hollowed by an axial bore 6 to lighten its weight as much as possible and still leave its wall of adequate thickness for strength and the designed head fastening, and its ends are wider recessed by a counterbore 7 to therewithin form an annular shoulder in said wall at a predetermined slight distance or depth from the extremities. Said shoulder, denominated 8, Within the ends is desirably made of a width corresponding substantially to the thickness of the wall in that portion which is reduced by the counterbore.

Applied to the ends of the barrel are transverse heads 9 of disk form. These heads are made of a material much harder than the barrel and preferably from a thin sheet metal which is light and tough or bend-resistant enough not to warp out of shape nor dent easily, and yet have a certain amount of resilience. In the sheet metal structure of this instance, the peripheral edge of the heads is rolled on the outer side into a rigidifying and strengthening bead 10 which also provides a smooth rounded rim of crosssectional dimension equal to that of the ordinary plate head. From a central'oril'loe l1 therein of a size to correspond with the barrel end openings, there extends laterally on the inner side 'a collar 12 like the hub of a wheel (see Fig. 3), shown formed together with said orifice by pressing out the center portion of the heads. This collar,A thereby made integral with the head, is shaped to fit into the wider recess or counterhore part of said barrel openings, and its extended end is bent inward in provision of a ila-nge 13 adapted to bear upon the shoulder: (8) inside the barrel. From said flange a plurality of short tines 14, numbering three in this instance at triangular disposal, extend so as to engage in the wall of the barrel as the collar is forced into place.

The head at each. end of the barrel is fastened into place thereon by a plug 15, which is desirably of the same material as the barrel, or Wood in this instance. This plug has a head portion 16 adapted to fit within the collar (12) of the head, and a reduced neck or shank portion 17 adapted to t into the axial bore (6) of the barrel, with a shoulder 18 between the two portions bearing upon the ange (13) of said collar. An axial bore `19 therein advantageously adapts the plugto serve as a spindle bearing for the spool in addition to fastening the head in place. It is also desirably beveled around the shank end edges as shown, for greater facility of insertion into the barrel. Said plug is pressed to position forcing the head tight against the end of the barrel. with the aforesaid flange end of the collar seating firmly upon the opposed inner shoulder (8) and the tines (14) engaging or impressing into the wall of the same (see Fig. 2), in which it is eifectually secured against loosening or pulling out as by a hard-drying cement or glue applied to its outer surface and/ or to the inside of the barrel.

In assembly of the parts, the head is simply placed on the barrel end with its collar inserted into the opening therefor, and the glue-coated plug then is applied to the described fastening position through its aforementioned central orifice, under force compressing said parts firmly together. Fig. 1 illustrates this relation of the assembly. The head is thus xed or united securely to the barrel as result of the vise-like bearing upon the flange end of its collar and will not separate therefrom unless the spool is broken apart by abnormal stresses, while the tines engaged in the barrel body prevent its turning on the barrel. This correlation of such few parts so easily formed provides an extremely simple and strong construction of very inexpensive manufacturing cost. The spool produced has the added advantage of quality to run true on spindle supports.

Fig. 4 illustrates a slight modification, wherein the head portion of the plug, instead of being trimmed off to the level of the metal head face, is extended beyond said face as indicated at 20, in this instance flush with the outer rim edge of the head, so as to be interchangeable with ordinary plate or thick headed spools of the same size on spindle racks and other mill machinery. This of course does not affect the structure in any way, but is an important feature part of the improvement.

It will be understood that various other modifications or changes in form and arrangements of the parts may be made without departingt from the scope of the invention. For example, the bores of the barrel, the inner shoulder thereof and the head 'collar and plug might be made polygonal instead of annular as shown, or the head of the plug might be tapered so as to compress within said collar and so tend to expand the same against the Wall of the barrel. As a further example, the flange of the collar might be turned out instead of inward, so as to engage in a groove formed in the barrel in place of the described shoulder with equivalent result. The invention accordingly is not intended to be limited by the appended claims to the specific construction or form illustrated.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United states is:

1. In a spool, a barrel, and a head of relatively harder material fitted to and engaging in the barrel in a press fastening thereto with portions of a tooth-like character at one end thereof extending into the barrel in the direction of its axis.

2. In a spool, a barrel, and a head having integral lateral means of fastening into the barrel by press engagement therewith interiorly; said lateral means having tapering projections extending into the barrel in the direction of its axis.

3. In a spool embodying a barrel, a sheet metal head having integral means of fastening to the barrel, comprising a lateral hollow annulus extending from a central orifice therein; said annulus being fianged at its end and having tapered tabs or pieces projecting therefrom in the direction of the annulus engaging in the Wall of the barrel around the central orifice of the same.

4. A spool comprising a barrel, a head of harder material having a hollow lateral part fitting into the barrel, said lateral part having a flange at its end bearing upon a shoulder' in the barrel and projecting tooth-like portions on the flange engaging in the body of the barrel, and a plug ttably extending through the lateral part into the barrel and holding said part of the head pressed in place with its flange tight against the barrel shoulder and said projecting portions impressed into the barrel body.

5. A spool comprising a barrel having a recessed end with a shoulder therein, a head of harder material having a laterai end-flanged collar extending from a central orifice therein fitting into said recess with its end against said shoulder and prong projections from the collar engaging in the wail of the barrel in the direction of its axis, and a plug fitting in the barrel end and collar through said orifice of the head secured in position holding the collar pressed in the stated fit.

6. A spool, comprising a barrel, a head on the end thereof and a plug fastening the head thereto; said head consisting of a sheet material in the form of a disc having a hollow lateral annulus extending from a central aperture therein fitted into the barrel and a reinforcing rim formed by turning the marginal portions thereof beyond the circumference of the barrel, a flange in the free end of said annulus, and tooth-like portions projecting from said ange parallel to the axis of the annulus.

7. A spool, comprising a barrel having a shoulder therein, a head on the end of the barrel and a plug fastening the head thereto; said head consisting of a sheet metal disc having a lateral hollow extension from a central aperture therein fitting into the end of the barrel, a flange on the end of said collar substantially parallel to the face of the disc, and tooth-like portions projecting from an edge of said flange in the direction of said extension; said plug being inserted through said aperture and extension of the head into the barrel with its head portion fitting into and forcing the former into place thereon with the iiange of the extension pressing against the shoulder in the barrel and said projecting portions from the flange engaging in the wall of the barrel around the shank of the plug.
